The application of the water heater terminals and principles can be summarized as follows:

   
1, should be in accordance with the heater terminals marked the NL and ground symbol corresponding color other wire crimp.

   
2, laying PVC hard plastic tube, or deposited outdoor Ming. Shall not be laid at a high temperature and a place vulnerable to mechanical damage.

   
3, cut the wire insulation should not damage the wire core. The wires must be connected to the electric heater hot tin processing, or pressure line ends processing.

   
4 hard plastic line pipe to be deposited to the solar water heater bracket do waterproof bend. Waterproof bend to the junction box of the heater section of the wiring required to wear bellows for protection.

   
Hard plastic tube connections must be securely sealed. For surface hard plastic tube application of steel pipe through the floor susceptible to mechanical damage protection, protection of the height of not less than 0.5m.

   
6, the hosts by three-pole plug sheathed cable links. In accordance with the NL and the ground symbol marked on the three-pole plug when the pressure line, must be a one-to-one correspondence with the pressure on the line terminals of the heater wire to prevent a short circuit caused the accident due to the pressure line.
